[0023] Example 1: Reference Figures 1 to 3A fixing bracket comprises two pads 1 and two bottom plates 2, the pads 1 and the bottom plates 2 are rotatably connected by a rotating shaft, two cooling fan bodies 6 are arranged between the two pads 1, and the two cooling fan bodies 6 are fixedly connected by screws, and the two cooling fan bodies 6 are provided with an L-shaped block 9 on the side away from each other, the tops of the two pads 1 are provided with a placement groove 10, and the bottoms of the two pads 1 are provided with a sliding groove 8, and the placement groove 10 is connected to the sliding groove 8, the L-shaped block 9 can be placed on the placement groove 10 and embedded in the sliding groove 8. The pad 1 and the base plate 2 are rotatably connected through a rotating shaft, so that the pad 1 can be flipped at a certain angle relative to the base plate 2. Two cooling fan bodies 6 are installed between the two pads 1. The two fan bodies are tightly fixed together by screws to ensure their stability during operation. The two cooling fan bodies 6 are equipped with an L-shaped block 9 on the side away from each other to further fix the fan body. A placement groove 10 is designed on the top of the pad 1 and a sliding groove 8 is provided on the bottom. The two grooves are interconnected. The L-shaped block 9 can be easily placed on the placement groove 10 and partially embedded in the sliding groove 8 to achieve preliminary positioning of the fan body.

[0024] Reference Figures 3 and 4 The L-shaped block 9 is provided with a movable groove 15. One side of the movable groove 15 is fixedly connected to a plurality of springs 14. One end of each of the plurality of springs 14 is fixedly connected to the same connecting plate 18. One side of the connecting plate 18 is fixedly connected to a limiting block 13, and the limiting block 13 penetrates the L-shaped block 9. The inner walls of the two sliding grooves 8 on the side away from each other are fixedly connected to a rack 19, and the two limiting blocks 13 engage with the rack 19. The springs 14 act together on a connecting plate 18, and one side of the connecting plate 18 is fixedly connected to a limiting block 13. The limiting block 13 can penetrate the side wall of the L-shaped block 9. A rack 19 is fixed on the side of the sliding groove 8 of the pad 1 away from the fan body. When the L-shaped block 9 is inserted into the sliding groove 8, the limiting block 13 engages with the rack 19.
